The throttling device uses a miniature controller to control the operation of
the step motor, thereby changing the pass-through area of the EEV to
regulate the ow of refrigerant.
● Check valve
Eectively prevents gas or liquid backow.
● Dryer lter
The lter dryer absorbs water from the refrigerant pipes and lters out the
foreign matter, which reduces component damage rates and improves
operating eciency and reliability.
● Sight glass
Users can observe the refrigerant ow and gas-liquid content through the
sight glass to realize easy maintenance and system optimization.
● Electric heater
The positive temperature coecient (PTC) electric heater features quick start,
large heating capacity, and even heat dissipation. It has multiple protection
mechanisms to ensure the safe and stable running of the equipment.
●
Humidier
Controls the humidity in an equipment room.
● Water pump
Drives the drainage.
● Display
The LCD is a 7-inch color touchscreen that allows for query, setting,
monitoring, and maintenance.
